Abstract
OBJECTIVE To investigate the effect of high mobility group protein box 1 (HMGB1) on apoptosis of astrocytes after oxygen glucose deprivation/reoxygenation (OGD/R), and to investigate the possible mechanism by evaluating the expression of apoptosis related protein Bcl-2 and Bax. METHODS The cerebral cortex astrocytes of neonatal rats were divided into normal group, model group, interference group and control group. Lentivirus vector of rat HMGB1 short hairpin RNA (shRNA) was used to suppress the HMGB1 protein expression in the astrocytes. Then the detection was made after astrocytes were deprived of oxygen and glucose 6 h, reoxygenation for 24 h. The effect of RNA interference was evaluated by Western blotting. The cell survival rate was measured by MTT assay. The apoptosis of astrocytes was determined by TUNEL assay. The expressions of Bcl-2 and Bax were detected by Western blotting. RESULTS Compared with the normal group, the protein expression of HMGB1 was significantly increased in model group after OGD/R (P<0.001), the astrocytes survival rate was decreased (P<0.001), the number of apoptotic cells labeled with TUNEL was increased (P<0.001), and the ratio of Bcl-2/Bax was decreased (P<0.001). Compared with the model group, RNA interference effectively inhibited the expression of HMGB1 in interference group (P<0.001), the astrocytes survival rate was increased (P<0.001), the number of apoptotic cells labeled with TUNEL was reduced (P<0.01), and the ratio of Bcl-2/Bax was increased (P<0.001). CONCLUSION The apoptosis of astrocytes can be induced by HMGB1 after OGD/R, and the mechanism may be related to regulating the expression of apoptosis related proteins Bcl-2 and Bax.

Abstract
Sirt1 promotes odontoblastic gene expression in human dental pulp cells, whereas the inhibition of Sirt1 downregulates the expression of those genes. To investigate whether the overexpression of Sirt1 in mesenchymal stem cells (MSCs) driven by Prx1 promoter could rescue the dentin formation defects in Bmi1-deficient (Bmi1-/-) mice, we established the MSCs overexpressing Sirt1 in Bmi1 knockout mice (Sirt1TGBmi1-/-). First, we used Prx1-Cre/ROSAnTnG mice to demonstrate that Prx1 linage cells exist mainly in the pulp horns at 4 wk of age. Second, we found that 4-wk-old Sirt1TG mice had increased tooth volume as compared with wild-type (WT) littermates. The expression level of Sirt1 was significantly higher in dental papilla mesenchymal cells of Sirt1TG mice than WT mice. Furthermore, we demonstrated that the tooth mineralization, dental volume, dentin sialoprotein-immunopositive areas, odontoblastic gene expression, and percentage of proliferating BrdU-positive cells were significantly elevated in the Sirt1TG mice and dramatically reduced in the Bmi1-/- mice versus the WT littermates at 4 wk of age. However, the areas of predentin and the percentage of TUNEL-positive apoptotic cells were significantly reduced in the Sirt1TG mice but dramatically increased in the Bmi1-/- mice as compared with the WT littermates. All these parameters were rescued in the Sirt1TGBmi1-/- mice versus the Bmi1-/- mice. Finally, by using dental papilla mesenchymal cells, we found that the overexpression of Sirt1 rescued the reduced cell proliferation and differentiation and increased the cell apoptosis caused by Bmi1 deficiency, which was associated with increased p53 deacetylation. Therefore, this study indicates that Sirt1 is a potential therapeutic target for promoting dentin formation in an anabolic approach to the treatment of dental developmental defects.

Abstract
BACKGROUND Measurements of transepidermal water loss (TEWL) and stratum corneum (SC) hydration are important for assessing epidermal functions. However, the availability of reliable and user-friendly devices, which can simultaneously measure both TEWL and SC hydration and can allow health providers to remotely access data in time, is limited. MATERIALS AND METHODS GPSkin Barrier® was compared with MPA5 system in the measurements of TEWL and SC hydration on the cheek, the dorsal hand, and the forearm in 200 normal volunteers, including 126 females and 74 males, aged 1-78 years with an average age of 45.24 ± 1.04 years. Correlation of data measured with MPA5 system and GPSkin Barrier® was determined. RESULTS Levels of both TEWL and SC hydration measured with the Barrie GPSkin Barrier® were lower than that with MPA5 system on all 3 body sites except for hydration on the cheek. The levels of both TEWL and SC hydration measured with GpSkin Barrier® were correlated well with that measured with MPA5 system on all 3 body sites CONCLUSIONS: GPSkin Barrier® is a reliable, affordable, and versatile device for assessing epidermal permeability barrier function and SC hydration.

Abstract
Achyranthes bidentata Blume (AB) is a health food and a sulfur-free herbal medicine that is one of the most heavily sulfur-fumigated herbs in the marketplace. In this work, a comprehensive approach using ultra-performance liquid chromatography coupled with quadrupole time-of-flight-MS (UPLC-Q-TOF-MS) and multivariate statistical analysis was developed to identify characteristic sulfur-fumigation markers, elucidate chemical transformation mechanisms and characterize the degree of sulfur-fumigation of AB. Non-fumigated and sulfur-fumigated AB samples were compared by UPLC-Q-TOF-MS/MS analysis. Three triterpene saponins (Betavulgarosides II-IV) and two amides (Feruloyl-4-O-methyldopamine and Moupinamide) were identified as characteristic markers, which were positively correlated with two active AB components, namely oleanic acid and ferulic acid, respectively. Moreover, the extent of the sulfur-fumigation under different weight ratios of sulfur to herbal materials (1:20, 1:40, and 1:80) was analyzed based on chemical transformations and sulfur dioxide residues. Further verification showed that the ratio of 1:40 within 1 h was reasonable and efficient for herb quality preservation and assurance. This study provides a reliable sulfur-fumigation protocol for the quality control of AB and other herbs.

Abstract
Gastrodia Rhizoma is one of the most heavily sulfur-fumigated edible and medical herbs in the marketplace. We developed a practical protocol using an ultra-performance liquid chromatography coupled with quadrupole time-of-flight-MSE (UPLC/QTOF-MSE)-based metabolome and health risk assessment model to identify characteristic sulfur-fumigated markers, dissect chemical transformation mechanisms, and control the quality of sulfur-fumigated Gastrodia Rhizoma. Two sulfur-containing p-hydroxybenzyl products, one sulfur-containing disaccharide, one glycolipid, and two phospholipids were selected and identified as markers based on multivariate statistical analysis. In particular, the sulfur-containing markers p-hydroxybenzyl hydrogen sulfite and trace p-mercaptobenzyl hydrogen sulfate were positively correlated with the active major phenolics. Moreover, a practical index the time of the minimum content was useful for evaluating the extent of the sulfur-fumigation under different weight ratios of the sulfur to herbal materials (1:20, 1:40, and 1:80). Ultimately, the 1:40 ratio within 1h of sulfur-fumigation was considered as safe and efficient for herb quality preservation under the maximum residue limit of 750mg/kg. This study shows that the practical protocol-based discriminated markers and practical limits can be applied to quality assurance of sulfur-fumigation and non-fumigation Gastrodia Rhizoma and other edible or medical materials.

Abstract
Background The optimal chemotherapy regimen administered currently with radiation in patients with stage III non-small cell lung cancer (NSCLC) remains unclear. A multicenter phase III trial was conducted to compare the efficacy of concurrent thoracic radiation therapy with either etoposide/cisplatin (EP) or carboplatin/paclitaxel (PC) in patients with stage III NSCLC. Patients and methods Patients were randomly received 60-66 Gy of thoracic radiation therapy concurrent with either etoposide 50 mg/m2 on days 1-5 and cisplatin 50 mg/m2 on days 1 and 8 every 4 weeks for two cycles (EP arm), or paclitaxel 45 mg/m2 and carboplatin (AUC 2) on day 1 weekly (PC arm). The primary end point was overall survival (OS). The study was designed with 80% power to detect a 17% superiority in 3-year OS with a type I error rate of 0.05. Results A total of 200 patients were randomized and 191 patients were treated (95 in the EP arm and 96 in the PC arm). With a median follow-up time of 73 months, the 3-year OS was significantly higher in the EP arm than that of the PC arm. The estimated difference was 15.0% (95% CI 2.0%-28.0%) and P value of 0.024. Median survival times were 23.3 months in the EP arm and 20.7 months in the PC arm (log-rank test P = 0.095, HR 0.76, 95%CI 0.55-1.05). The incidence of Grade ≥2 radiation pneumonitis was higher in the PC arm (33.3% versus 18.9%, P = 0.036), while the incidence of Grade ≥3 esophagitis was higher in the EP arm (20.0% versus 6.3%, P = 0.009). Conclusion EP might be superior to weekly PC in terms of OS in the setting of concurrent chemoradiation for unresectable stage III NSCLC. Trial registration ID NCT01494558.

Abstract
Biphenyls are unique phytoalexins de novo synthesized in plants in response to pathogen attack. These compounds are found in Maloideae, a subfamily of the Rosaceae. The anti-microbial activities of biphenyls have been reported in a number of studies and they appear to represent an important defense strategy against pathogens common in the Maloideae, such as species in Malus, Pyrus, Sorbus, and Chaenomeles. Here, cell suspension cultures of Sorbus pohuashanensis were established to study biphenyl phytoalexins formation after yeast extract (YE) treatment. An ultra-performance liquid chromatography (UPLC) method coupled with quadrupole time of flight mass spectrometry (Q-TOF-MS) LC−MS/MS was applied to determine the time course of these biphenyl biomarkers accumulation in YE-treated S. pohuashanensis suspension cells. The results of quantitative analyses show the content of Noraucuparin, 2′-Hydroxyaucuparin, and their glycosides initially increased, then decreased over time. The Noraucuparin content reached its highest (225.76 μg·g−1) at 18 h after treatment, 6 hours earlier than that of Noraucuparin 5-O-β-d-glucopyranoside. The content of 2′-Hydroxyaucuparin reached its highest (422.75 μg·g−1) at 30 h after treatment, also earlier than that of its glycoside. The understanding of phytoalexin metabolism in this study may provide a basis for improving Maloideae resistance to pathogens.

Abstract
BACKGROUND AND PURPOSE Posterior reversible encephalopathy syndrome is a clinicoradiologic entity with typical MR imaging showing predominant vasogenic and occasional cytotoxic edema. It is unclear whether MR imaging correlates with levels of serum albumin. We determined potential risk factors for development of cytotoxic edema in posterior reversible encephalopathy syndrome. MATERIALS AND METHODS Seventy-nine cases with typical clinical symptoms and characteristic neuroradiologic findings conformed to posterior reversible encephalopathy syndrome diagnostic criteria and were included in this study. FLAIR, DWI, and ADC maps were interpreted to evaluate the severity and type of edema. MR imaging was correlated with the levels of serum albumin, and cytotoxic edema was compared with the location and severity of brain edema. RESULTS Pure vasogenic edema was found in 53 cases (67.09%), and vasogenic edema complicated with cytotoxic components, in 26 patients (32.91%). There was no difference in serum albumin levels between patients with cytotoxic components and those with vasogenic edema (P = .983). There was a significant difference in the edema scale scores between patients with cytotoxic edema and those with vasogenic edema (P = .006). The percentage of cytotoxic edema located in the area with higher scale scores of edema was significantly larger than that in areas with lower scale scores of edema (P = .002). CONCLUSIONS Serum albumin may contribute to the development of edema in PRES but is not a decisive factor for edema type. Cytotoxic edema in posterior reversible encephalopathy syndrome is probably related to regional decreased perfusion and arteriolopathy. Further work should be undertaken to discover the pathophysiologic mechanisms involved.

Abstract
OBJECTIVE To understand formaldehyde residue in cosmetics, an investigation on formaldehyde release from eight preservatives (methenamine - MA, paraformaldehyde - PF, poly(p-toluenesulfonamide-co-formaldehyde) -PTSAF, quaternium-15 - QU, imidazolidinyl urea - IU, diazolidinyl urea - DU, dimethyloldimethyl hydantoin - DMDM and bronopol - BP) under various conditions was performed. METHODS The concentration of released formaldehyde was determined by high-performance liquid chromatography with photodiode array detection after derivatization with 2,4-dinitrophenylhydrazine. RESULTS The amounts of formaldehyde release were in the order of PF > DU > DMDM ≈ QU ≈ IU > MA > BP > PTSAF. The releasing amounts of formaldehyde were the highest in the presence of aqueous matrices for the releasers except QU and IU, and the releasing effect was also relative to pH. More formaldehyde was released with longer storage time and higher temperature. Furthermore, all preservatives in cosmetic matrices released fewer amounts of formaldehyde than in pure aqueous or organic matrices, and the formaldehyde-releasing amounts were also cosmetic specific. CONCLUSION Formaldehyde release was dependent on the matrix, pH, time and mainly temperature, and the releasing effect was also cosmetic specific.

Abstract
We aim to identify the effects of food on the pharmacokinetics (PK) of amlodipine, losartan and losartan's active metabolite (EXP3174) after oral administration of the Compound Amlodipine Tablets with single dose in healthy Chinese subjects. 12 subjects took the compounds (10 mg/100 mg, amlodipine/losartan) at the conditions of a high-fat breakfast and an overnight fast with a washout period of 14 days. Plasma samples were obtained at scheduled time, and determined by HPLC-MS/MS for the concentrations of amlodipine and HPLC-MS for the concentrations of losartan and EXP3174, respectively. PK parameters were calculated using Software Drug and Statistics (Version 2.0). When tablets were co-administered with food, there was no significant difference of AUC for amlodipine and losartan, but the AUC of EXP3174 was reduced by 19.1%. Meanwhile, the Cmax of amlodipine, losartan and EXP3174 were reduced by 11.4%, 20.0% and 41.4%, and the Tmax of losartan and EXP3174 were 1.3 and 1.8 h longer, respectively. No significant difference was found at t1/2 following food intake. In conclusion, the Compound Amlodipine Tablets, are affected by food administration by reducing the AUC of EXP3174. It is thus suggested that the Compound Amlodipine Tablets should be administered 1 h before or 2 h after meal.
